CORE MEMBER Original Filed Aug. 15, 1936 INVENTOR. P055? T' C. P/ERCE ATTORNEYS Patented Apr. 25, 1939 UNITED STATES PATENT OFFICE GORE MEMBER Robert 0. Pierce, Niles, Mich assignor to National Standard Company, Niles, Mich, a corporation of Michigan 2 Claims.

This invention relates to core. members and more particularly to core members for weather strips, window channels and the like.

An object of the invention is to provide a novel and efiective core member for a weather strip so constructed as yieldingly to hold the weatherstrip in sealing engagement with the member to be sealed.

Another object of the invention is to provide a core member in which an elongated cordlike element is formed with a series of overlapping loops of resilient wire or the like extending laterally therefrom. Preferably the loops are formed by separate wires wound about the cordlike element in overlapping relation so that the loops mutually brace and support each other.

The above and other objects and novel features of the invention will be apparent from the following description of the illustrative embodiment shown in the accompanying drawing, in

which:

The figure is a side view with parts in section or a weather strip element embodying the in-' vention.

The member includes an elongated cordlike element or core ill of twisted paper, hemp or the like having a pair of resilient wires H and I2 wound therearound in the form of overlapping loops. The loops are formed by the different wires alternating along the length oi! the strip. That portion of the loops adjacent the element III has been compressed around the element as indicated at I3 and preferably stretched beyond 35 back and the remainder of the loops has been 40 The element l0 may be enclosed by a tubular the elastic limit of the wires so it will not spring cover l5 of rubber or the like slit along one side to permit the loops I l to project through and a fabric cover It may enclose the entire assembly. The cover i6 is preferably stitched at l1 and may, if desired, have other seams therein where it projects outwardly of the element III, the covered projecting loops forming a resilient attaching flange.

As can readily be seen, this overlapping of the loops results in mutual support resulting in a sturdy but resilient core member for a weatherstrip.

This application is a division of applicant's copending application Serial No. 96,194, filed August 15, 1936, now matured into Patent No. 2,131,069, issued September 27, 1938.

While one illustrative embodiment has been shown and described, it is not intended that the scope of the invention be limited to the form shown nor otherwise than by the terms of the appended claims.

What is claimed is:

1. An elongated core-member comprising a cordlike element of considerable length, a plurality of resilient wires having portions encircling and compressing said element at evenly-spaced points, said wires forming overlapping laterallyextending loops all of which are on the same side. of the element.

2. An elongated core member comprising a cordlike element of considerable length, a pair of resilient wires having portions encircling and compressing said element at evenly-spaced points,

, said wires alternately forming laterally-extending loops all of which are on the same side of the element and each of which overlaps the adjacent loops.
